pixesl to yards

[dthrasher90]

Is there a way to make a converter to say like, if your person moves 5 pixels, that would digitally represent 1 yard?

Yeah

function pixelsToYards(pixels)

{

      return pixels/5;

}

Is your problem more complex then that.

Thanks!  Not more complex at all.  I was thinking the solution would be more complex than this.

Use a globally accessible function to multiply by a constant coefficient - thereby converting between pixels and yards etc.

But if wanting to convert back from yards to pixels in a reliable way be mindful that, in programming, not all floating point coefficients are accurately reversible.

Another approach is to keep your game units independent of pixels, and only convert them to pixels when it's time to draw something involving pixels.

Yeah, its just so I can log game state, I physically do not want to change the canvas, just want the player to feel like yards are being measured on it.
